Diggester writes: "Back in July 2010, the United Stated government approved few exemptions in a federal law which made jailbreaking/rooting of electronic devices(iPhones and Android devices) legal. The court ruling stated that every three years, the exemptions have to be renewed considering they don't infringe any copyrighted material.

The three year period is due to expire and Electronic Frontier Foundation (EFF) is looking to get the exemptions renewed. In order to do so, they have filed a petition which aims at government to declare jailbreaking legal once again. In addition to that, EFF is also asking for a change in the original ruling to include tablet devices."Link to Original Source
